y Application mea my zo, 192s. serial No. stacca- My invention relates to line lock, space key and case shift mechanisms for typewriting machinesPand its chief object is tol provide new and improvedmechanisms of the character specified. v `To the above and other endswhich will hereinafter appear, my invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

My invention is-herein shown as applied to the newly marketed machine known as the Smith premier No. 60 typewriter,

Figure 1 of the drawings being a fragmentary front-to-rear vertical section-a1 v iew of one of said machines embodying my invention, only so nruch of themachine being shown as is necessary to a4 full understanding of the invention.

Figure 2 is a fragmentary vertical sectional view taken on a plane indicated by the i `section line 1-1 in Fig. 1.

Figure 3 is a transverse vertical sectional' vie-w taken on a plane designated by the section line 2 2 in Fig. 1 and looking in the direction ofthe arrows at said line. i' Figures aand 5 are fragmentary. views of` certain of the line lock devices.

The. main frame of the machine comprises a rectangular base portion 1 from which rise posts 2 supporting a top plate 3.v From the top plate rise goose-neck b rackets 4 to which 'are secured fixed track bars or guide rails `5 and 6 that are oppositely Igrooved and cto-operate through anti-friction rollers 7 with the oppositely grooved top and' bot- Atom portions of a rear bar 8 that is part ofatraveling carriage. Said carriage further includes end bars 9 that extend forward from the end portions of the rear bar Sand support a rotary platen or cylinder 10. The. platen carrier or carriage 8, 9is constantly.

urged leftward by a motor or spring drum (not shown), such movements being controlled by carriage feeding devices or escapement mechanism comprising a toothed escapement wheel which is fragmentarily` shown in Fig. 1 and 4designated by the nu'- nieral 1 1.l (lo-operative with said escapement whebl are escapement dogs 12 and 13 mounted at the top of the upright arm 14 of a dog rocker pivotedat l5 and having a forwardly extending horizontally` disposed r the space barof the machine.

arm 16, saiddog rocker being actuated as tending link 20 with the upright arm of an angular sublever 21 which is pivotally supported on a key lever (not shown) and cooperates with a fixed, abutment or cross rod supportedin the base 1. When any print- Ving key is actuated it is effective through the described train of connections "compris- 4ing its sublever 21 and link 2 0 vto actuate f the connected type bar 17, causing it to swing upward and rearward on .its pivot 18v to co-act with the front face'of the` platen 10. Each ty e bar is provided with a lower case type an an upper case type, and when the parts are related asin Fig.y 1 the inner or lower case type o f the type bar will coact with the platen. y

Means are provided for shifting the .typo bar support or segment 19 to change case, said segment. in the presentinstance being shifted'downward to change from iower to upper case. To thisendthe segment is slnftably mounted, being provided at its right and left-hand sides with grooved track ways 22 which co-o erate with antifriction rollers 23, Saidv operating with stationary grooved ways in upright guide posts 24 secured to the base 1. top devices are provided for limiting the up and down movements of the segment on the guide posts, said stop devicescomprising stop lugs 25 and 26,on the segment and co-operating stop arms 27 and 28 mounted on the posts. It will be understood that there are sets of these stop devices at both sides of the segment. Normally the'segment is maintained in the Figs. 1-2l position with the stops 26 and 28 cont-activelyy engaged by means comprising a coiled spring 2Q which is connected with the`segment las presently` to be described and -at its rear end is anscrew which furtherl comprises va shank or ro 1ers likewise copivot portion 32, said screw being supported on parallel ears 33 comprised in an angular bracket 34 which further comprises a vertically extending comb portion '35,' the 'bracket being secured by screws 35a to a boss 1a on the under` side of the roof portion of the base 1. The slots in the comb plate 35 receive and guide the rear end portions of two shift levers 36 and 37 which are pivotally mounted on the shank 32 and are maintained in normal position, Fig. 1, by

lmountedon pivots 42a secured in the sides of the base 1. The crank arm 41 is of sheet metal and fits loosely over the rock shaft 42 but is secured by a screw 43 to a cast metal crank arm 44 of considerable thickness that is fixed to the shaft 42 by a cross in 45. The cross pin projects downward and is formed with a groove over which the forward end portion of'the spring 29 is looped. It will be understood that the described construction of the roller 39 and the crank arms 41 and 44 and the spring 29 is duplicated at the opposite side of the machine. Fixed to the rock shaft 42 inside each crank arm 44 is a crank arm 46 having a hub 47 which fits over the rock shaft 42 and is securedthereto as by'a cross pin. The rear end portion of the crank arm 46 has pivotally connected to it at 48 the lower end of a shift link 49, the upper end of which is pivoted at 50 to a lug 19a on the segment 19. There are two shift links 49. one at each side, and two crank arms 46. The construction is such that when one of the shifting key levers, as the left-hand lever 37, is dcpressed, it will press down the underlying roller 39 loweringthe crank arms 41 and 44 and rocking the shaft 42 which will in turn swing down the crank arms 46 causing the latter through the links 49 to shift the segment downward, the movement continuing until the segment is arrested by the engagement of the stops 25 with the frame stops 27. With the segment in this lower position, the upper case types on the type bars 17 will print when actuated.

The escapement devices are operated directly from the type bars 17 through means comprising a curved `universal bar 51 which is arranged in a groove 52 cut in theirear of the segment 19, said universal b'ar carrying a guide pin 53 which fits loosely in a hole 54 in the segment. lntegral with the universal bar 51 and extending rearward therefrom at its opposite lside portlons are arms 55 which fit into the forked rear ends of crank arms 56 and are pivotally connected thereto at 57. Said crank arms are fixed to and extend upward from a rock shaft 58 which takes bearings in a bracket 59 secured at the rear of the segment 19 and shiftable therewith. A short crank arm 60 rises from the rock shaft 58 at about its middle, said crank arm carrying a pin 61 which is engaged by the slotted or forked end of a push link 62, said link being also forked at its rear to engage With a headed pin 63 that extends laterally from an arm 64 secured to the upright arm 14 of the dog rocker. The construction is such that when one of the type bars 17 is actuated a nose portion 17a near its pivot will contact, as the type bar nears the end of its printing stroke, with the universal bar 51, moving said bar rearward, this movement being transmitted to the rocking frame or oscillator comprising the arms 56, rock shaft 58 and arm 60, the latter pushing the link 62 rearward and actuating the dog rocker. `Whcn thus actuated the upper arm 14 of said rocker will swing forward disengaging the dog 12 and engaging the dog 13 with the escapement wheel. The return movement of the dog rocker and the completion of the escapement operation is effected by the dog rocker restoring spring 65 which is arranged between the arm 14 and the dog rocker bracket 66. A stop screw 67 carried by the arm 14 limits movement of the rocker by contacting with the bracket 66. It will be observed that the universal bar.51 is operated directly by the type bars to actuate theescapement mechanism during printing operations through a train of connections comprising the described rocker frame and the link 62. l

A separate train of connections is employed for actuating the escapement mechanism from the space bar of the machine, said space bar 68`being carried by a pair of spacing levers 69 which are necked to tit over'V and bear on the rock shaft 42. rlhe levers 69 terminate a short distance back of said-rock shaft and are connected by a cross rod 70 which has fixed to it a crank arm 71 carrying an adjustable Contact screw 72 that co-operates with a horizontal lip portion 73 extending over the point of the screw from a lever member 74 that is pivoted or fulcrumed at 75 to a lever 76 included in the ribbon vibrating mechanism, said lever 76 -having a stationary fulcrum 77. Plvotally link upward. The construction y:is such that when the space bar 68 is depressed the contact screw 72 carried by the cross rod 70 will be raised, and acting against the lip 73 will rock the lever 74 and lower the link' 79, causnected thus providing for the 4bell crankay rigidpivotal extension. The upright arm 103 of the bell 'crankis confined loosely between the lugs or stops 100 and 101, these parts limiting the pivotal movements of the ing its lip 80 to actuatethe dog rockerbell `crank which is normally maintained 14-16 and operate the ecapement independently of the universal bar 51 and its supporting or rocking frame, these parts remaining motionless by reason ot the loose connection ail'orded by the forked or slottedv link 62. Stops are provided for the space bar mechanism comprising a metal arm 85 secured to the under side of the space bar 68 and supporting a pad 86 which normally cooperates with the front portion of theubase 1 to maintain the space bar in normal position. The downward limit of movement is determined by a stop pad 87 mounted on an arm or bracket 87 a 'secured to the basel of the machine.

Theline lock mechanism is operated by contact devices which in the present case are mounted on the frame ot the machine being supported on a toothed bar 88 which is arranged above the upper track bar 6andhas its ends pivotally supported at 89. I Adjustably arranged on the stop bar 88 are a num.- ber of contact `devices or stopsicluding one numbered 90 which is `provided with two contacts or projecting lugs 91 and 92, the contact 91 being eiective to operate the bell ringing mechanism net herein shown, the other contact 92 actuating the line lock mechanism. Mounted adjustably on said stop bar 88 to the left of the device 90 is a contact deviceor stop member 93 provided witha lug or stop proper 94 which cowoperatea with the line lock mechanism to provide a tinal'stop for the line. There may be also provided a stop member 95 having a stop lug 96 and secured by screws 97 to the 'front of the track bar 6, which lug 96 iseifective to prevent accidental displacement of the carriage from its trackswaysin co-operation with the upstanding stop' 98 secured to the front of the carriage bar 8 by screws 99. In-

tegral with the stop 98 is a stop 100 which co-operates with an oppositely disposed stop lug 101 on the carriage to limit movements of the carriage carried line lock contact or stop member. Said member in the present instance is inthe form of ar bell crank 102 having an upstanding arm 103 and a rightwardly extending horizontally disposed arm 104'terminating in a rearward projection or lip 105. rlhe bell cranklever 102 is carried by a shouldered screw 106 which bearsin a boss or projection 107 on the carriage bar 8. The shoulder screw 106 passes in from the back, and its threaded shank projects forward out of the boss 107, the bell crank 102 being screwed or threaded on the shank and abutting against the shoulder ot' the screw so that the screw and bell crank are rigidly conagainst the stop 100 by a spring 108 that is coiled around the boss or hub 107, one of the ends of said spring engaging the upright arm 103 of the bell crank and urging it constantly leftward. The upper end or tip portion 103a of the arm 103 has a path of movement which is intersected or crossed bythe projections or contacts 91, 92 and 94, so that these contactsare effective during the carriage .travel to turn the bell crank onits pivot and throw the arm 10l1-downward. The back faces of the contacts 91 'and 92 are beveled so that during return movements of the carriage should the bell crank arm 103 start from a position at the left of thesevcontacts it lwill engage with that are threaded into the ends of the track bar 5 and serve aspivots for -the bail or bar. A`leaf spring 112 secured to the left-hand side of the top plate by screws 113 enga-ges at its free end with the under side of the bar 109 to maintain it in normal position and re store it after actuation. As clearly appears from. Fig. 1, the upper edge of the bar`109 lies beneath but out of contact with the contact portion 105 ot the `bell crank 102 so that these parts do not generate friction during traveling movements of the carriage. Near its middle the bar 109 is formed with a rearwardly7 bent lug or linger 114 which engages with a line locking device in the form of a hook member 115 that is pivoted on a shoulder screw 116 threaded into the front face of the track bar 5, the hook member being arranged between the track bar and the bail or bar 109. Said hookor member 115 is provided to the left ot its pivot or stationary mounting 116 with an extension or finger 117 which overlies the lug 114 o-ny the bail and is normally held up or sustained thereby so as tomaintain the hook member in the inclined position illustrated in Fig. 3. rThe lower end of said member terminates in la hook or engaging portion proper 118 and when in the inclined position, said hook 118 is held out of use or inoperative. llVhcn released. the member 115 swings through the force o t gravity rightward about the pivot 116 to render the hook 118 operative. Said hook is adapted to co-act with devices `on the two trains connecting the escapesaid rock shaft and providing a support for a second arm 120 terminating at the rear in a head or enlargement 121 formed with an opening or rectangular slot 122. The arm 120 is pivotally supported by a, screw pivot 123 on the arm 119 and is held in rigid relationship with said arm 119 by a clamping screw 124 which engages in a slotway 125 formed in the forward portion of the arm 120, the slot affording a limited adjustment or movement of the arm 120 on the pivot 123. The construction is such that when'the screws 123 and 124 are loosened, the relationship between the arms 119 and 120 may be varied by turning the arm 120 on its pivot 123 to desired position and thereafter tightening the two screws. By this means a close and exact relationship between the hook 118 and the arm 120 is obtained. The hook 118 likewise co-operates with a device on the' link 79, said device being inthe form of a T-shaped member comprising a body p01'- tion 126 from which projects -rearward a linger or extension 127. The body portion 126 is formed with a vertical slot 128 which receives a headed clamping screw 129 that is threaded into the link 79. When the screw is loosened the finger 127 may be adjusted up and down to the extent of the slot 128 and thus4 positioned properly to co-operate with the line locking'hook 115, 118.

In operation, assuming that the contact or stop members 90 and 93 have been properly adjusted to arrest the carriage at predetermined points and lock the line, determining the temporary and permanent ends of theline of writing, it will be understood that as 4 the carriage travels towards the left, the tip portion 103a of the bell crank 102 will cooperate with the contact 91 to ring the bell, after which said tip portion or contact 103a will engagewith the contact 92. The bell crank 102 as a consequence is swung on its pivot until the arm 103 is arrested by the stop 101, thus resulting in the arrest of the carriage, the' arm 103 being clamped or confined between the stops 92 and 101. As the bell crank 102 is swung on its pivot by the contact 92, the extension 105 moving downward will engage with the bar 109, swinging said bar .downward on its pivots and caus-k, a

`and 120. With the arm 120 1n its downing the finger 11.4 moving downward to release the finger or extension 117 and permit the hook member 115 through the force of gravity to swing rightward about the pivotal center v116 until the hook 118 underlies both the` bottom edge of the head 121 and the bottom edge of the finger 127, as illustrated in Fig. 4. With the parts in this rela-tionship, should one of the printing keys be depressed, throwing the associate type bar 17 towards the printing point, said type bar will engage with the universal bar 51 and tend to move the latter rearward, without effect however, since the universal bar is locked. In other words, the. movement of the universal bar will be prevented at this time by the hook 118, said hook preventing the arm 120 and its supporting arm 119 from swinging downward, thereby locking the shaft 58 from rocking and the crank arms 56 and 60 from swinging rearward. Thus the pivots 57 are held or locked, preventing operation of the universal bar and of the type bars, so that the link 62 can receive no motion from the pin 61 and the escapement is not operated. At the same time the finger 127 is prevented from being depressed by the hook 118 thus preventing lowering of the link 79, as well as rocking of the lever 74 and actuation of the space bar levers 69, the space bar 68 being locked as a consequence.

One advantage of the present construction is that accent or dead key type bars may be operated while the line is locked as dcscribed. An accent type lbar is illustrated in Fig. 1 and numbered 17", this type bar differing from the ordinary type bar in that it has no contact face or nose 17a to engage with and actuate the universal bar, this portion of the accent type bar being cut away. As a consequence the accent type bar may be thrown into actuating position without contacting with the universal bar 51, so that even though the universal bar be locked, it will not prevent actuation and printing of the accent type bar.

The line locking devices and the carriage may be released by swinging the stop bar 88 on its pivots and releasing the lever' 102 and the line lock devices to permit the carriage to advance under actuation of the printingr and space keys until finally arrested.

Provision has been made for assuring the effectiveness of the line locking mechanism should the type bars be in shifted or upper case position when the line locking lever 102 is operated as has been described. It will be understood that when the type bar segment 19 is shifted downward for upper ease, the universal bar and the rocking frame comprising the shaft 58 will be correspondingly shifted downward and that said shaft will carry downward with it the arms 119 most or shifted position the opening 122 will be brought opposite the locking hook'118, so that wher the line lock is actuated the hook, instead of co-'acting with the bottom edge of the head 121 as before, will engage with the top edge 122 of the opening 122 passing into-the opening for this purpose. Thus the arm 120 4is effectively locked against operation, as will clearly be understood from Fig. 5, whichshkows the parts in effective engagement'when the segment is f 122 which -is shiftable bodily with the segment is locked against such movement by the hook 118. With the parts in lower case position and the line locked, the hook 118 underlies the bottom edge of the head 121 thus preventing the arm 120 and the segment'lQ from being shifted downward should one of the shift keys be depressed. On the other hand when the segment is down in its upper case position and the line is locked, the hook 118 will be engaged in the opening 122 and the lower edge of said opening abutting against the under edge of the hook will prevent the return shifting movement to lower case position.

Certain features of'invention herein disclosed are not claimed, vas they constitute in part the subject-matter of my application,
